Recycled plastic (HDPE) coarse aggregate manufacturing method and performance in concrete

Abstract

The process for preparing plastic aggregate to be used in concrete mixtures, The plastic can be reprocessed plastic that has been broken into strips after being washed through the templates. Sand and plastic rock dust aggregates are strong contenders for concrete mixes. This article uses recycled plastic collected from a local plastic shredder, measuring between 1 mm and 6 mm, melted at a temperature between 294 and 339 °C, and mixed with sand and rock dust. Here in this paper, scanning electron microscopy (SEM). And Elemental identification and quantitative composition information are also obtained using an “energy-dispersive X-ray analyzer” (EDX. or EDA). The size of the aggregates manufactured in the beginning varies. between 2.36 and 20 mm, which is covered with a granulometry under the ASCE-C330, C33-99a, and IS 383-2019 standards. In concrete, by use of light-weight plastic aggregates, as well as the use of high-density plastic materials to prepare plastic aggregates (single and well-graded), the method of manufacturing plastic aggregates for civil infrastructure, and the composition that incorporates this type of aggregate, are the concepts of this research.
